sorry for the inconvenience.
I have installed the debug kernel and did your tests with it.
Attached you'll find 6 files:
file1before is the output of dmesg -c before I plugged in the device.
file2before is the output of cat /proc/partitions before I plugged in the
device.
file3before is the output of lsmod before I plugged in the device.

file1after is the output of dmesg -c after I plugged in the device.
file2after is the output of cat /proc/partitions after I plugged in the device.
file3after is the output of lsmod after I plugged in the device.
